Also known as crusted scabies, the severe infection is caused by microscopic mites which burrow under the skin and give the appearance of thick, warty crusts.

The home delivers high level and specialist end-of-life care from a converted country manor.

One resident has been officially diagnosed with the condition after displaying eczema-like symptoms. It’s not known how the disease was contracted, and there are fears it could spread to other residents and staff.

People with a weakened immune system are particularly susceptible, including the elderly and those taking medicines that suppress their immune system.

Agencies with responsibility for health have also been notified including the Care Quality Commission (CQC), which regulates healthcare, and Public Health England.

A spokesman for the independent healthcare provider Four Seasons Health Care, which runs the home, said: “FSHC followed policy and procedure for dealing with scabies, and notified CQC, Public Health England, Clinical support nurse for Infection, Prevention and Control for Warwickshire and Coventry, who advised the home accordingly.

"Relatives of other residents and their GPs were also notified. As it stands, there is only one confirmed diagnosis of this case.

“Norwegian scabies is a rare type that affects people who have a weakened immune system, including some elderly people and those taking medicines that suppress their immune system.

"It is treated with creams or lotions.”

A CQC spokesman said: “CQC are aware of the scabies outbreak and are keeping in touch with the home about this.

"As with all services we regulate, CQC continues to monitor this service and its compliance with the national standards of quality and safety.”
